Hospital workers mental health during the COVID-19 pandemic: methods of data collection and characteristics of study sample in a university hospital in Milan (Italy).

BACKGROUND: The COVID-19 pandemic is currently a severe challenge for healthcare workers, with a considerable impact on their mental health. In order to focus preventive and rehabilitation measures it's fundamental to identify risk factors of such psychological impairment. We designed an observational longitudinal study to systematically examine the psychological wellbeing of all employees in a large University Hospital in Italy, using validated psychometric scales in the context of the occupational physician's health surveillance, in collaboration with Psychiatric Unit. METHODS: The study started after ethical approval in August 2020. For each worker, the psychological wellbeing is screened in two steps. The first level questionnaire collects sociodemographic characteristics, personal and occupational COVID-19 exposure, worries and concerns about COVID-19, general psychological discomfort (GHQ-12), post-traumatic stress symptoms (IES-R) and anxiety (GAD-7). Workers who score above the cut-off in at least one scale are further investigated by the second level questionnaire composed by PHQ-9, DES-II and SCL-90. If second level shows psychological impairments, we offer individual specialist treatment (third level). We plan to follow-up all subjects to monitor symptoms and possible chronicization; we aim to investigate potential risk factors through univariate analysis and multivariate logistic regressions. RESULTS: Preliminary results refer to a sample of 550 workers who completed the multi-step evaluation from August to December 2020, before vaccination campaign started. The participation rate was 90%. At first level screening, 39% of the subjects expressed general psychological discomfort (GHQ-12), 22% post-traumatic stress symptoms (IES-R), and 21% symptoms of anxiety (GAD-7). Women, nurses, younger workers, subjects with COVID-19 working exposure and with an infected family member showed significantly higher psychological impairment compared to colleagues. After the second level screening, 12% and 7% of all workers showed, respectively, depressive and dissociative symptoms; scorings were significantly associated with gender and occupational role. We are currently extending sample size and evaluating subjects over a period of further 12 months. CONCLUSIONS: The possibility to perform a systematic follow-up of psychological wellbeing of all hospital workers, directly or indirectly exposed to pandemic consequences, constitutes a unique condition to detect individual, occupational, and non-occupational risk factors for psychological impairment in situations of prolonged stress, as well as variables associated with symptoms chronicization.

Anorexia of Aging Associated with Nutrients Intake in Brazilian Elderly.

This study evaluated the association between anorexia of aging and nutrients intake. It was a cross-sectional study with 130 individuals aged 60 years or older, undergoing outpatient care in the city of Campinas, São Paulo. Anorexia of Aging (AA) was assessed using the Simplified Nutrition Appetite Questionnaire (SNAQ), and food consumption was evaluated using the 24-hour recall (24HR). The prevalence of AA was 27.7%, in which 66.7% were women and 38.9% were older than 80 years. Elderly with AA presented lower intake of calories (1172.6 kcal vs 1477.9 kcal; p = 0.003), carbohydrates (158.5 g vs 194.1 g; p = 0.015), proteins (49.9 g vs 68.5 g; p = 0.004) and lipids (34.6 g vs 46.1 g; p = 0.006). They also had lower intake of fibers (12.6 g vs 19.4 g; p < 0.001), iron (6.4 mg vs 8.9 mg; p < 0.001) and zinc (6.0 mg vs 8.5 mg; p = 0.004). Our results show that intake of most nutrients is significantly lower in AA elderly, except carbohydrates, which may point to worse-quality diets. The diagnosis of AA, as well as the evaluation of elderly food intake, are essential to prevent undernutrition, vulnerabilities, and increased morbidity and mortality.

Effect of Spacer Length and Solvent on the Concentration-Driven Aggregation of Cationic Hydrogen-Bonding Donor Polythiophenes.

Aggregation of cationic isothiouronium polythiophenes with alkoxy-spacers of different lengths at the 3-position of the thiophene ring was studied in solvents of different polarities. Hydrogen-bonding capacity was assessed by steady-state absorption and fluorescence spectroscopy, whereas the aggregation in aqueous solutions was studied by electron paramagnetic resonance spectroscopy, using paramagnetic probes of different polarities. The two polymers displayed similar features in respect to conformation, effect of cosolvents on aggregation, unstructured absorption-fluorescence spectra, Stokes shifts when aggregated, solvatochromic effect, and self-quenching concentration. However, these polymers also showed different specific interactions with water, Stokes shifts in water, effect of the solvent on the extent of dominant state of the S1 level, and also different inner cavities and hydrophobic-hydrophilic surface area in aqueous solution aggregates. Water maximized the difference between the polymers concerning the effect of specific increases in concentration, whereas the presence of 1,4-dioxane generated almost identical effects on both polymers.

Controlled Versus Uncontrolled Resistant Hypertension: Are They in the Same Bag?

PURPOSE OF REVIEW: Resistant hypertension (RHTN) is a condition in which besides the antihypertensive therapy using at least three different drugs (including a diuretics), brachial blood pressure does not reach the target (e.g., 140/90 mmHg). RECENT FINDINGS: Despite the diversity of clinical presentations, we divide RHTN in two major groups according to blood pressure and number of drugs taken: controlled (C-RHTN) and uncontrolled (UC-RHTN) resistant hypertension, with refractory hypertension (RfHTN) included in the latter subgroup. Both C-RHTN and UC-RHTN are heterogenic and complex syndromes. To better approach this matter, the some pathophysiological mechanisms (increased volemia, hyperactivity, plasma cortisol, adipocitokines, and other pro-inflammatory factors), have a pivotal clinical role. Some features (African ethnic, obesity, age > 60, LV hypertrophy, and vascular stiffness) increase the risk of refractoriness as well as worst prognosis. Based on increased target organ damage, cardiovascular risk and events will be addressed in this review. Our conclusion is that although both C-RHTN and UC-RHTN are extreme phenotypes of hard-to-control BP, some mechanisms of the disease and clinical expressions are distinct. According to these differences, "UC-RHTN and C-RHTN are not in the same bag."

Depression severity and concentration difficulties are independently associated with HRQOL in patients with unipolar depressive disorders.

PURPOSE: Cognitive impairment is a core feature of major depressive disorder (MDD), and dysfunctions in this area strongly contribute to MDD-associated disability. Whether cognitive impairment has an independent clinical course and a unique impact on HRQOL is still debated. We sought to characterize the relationship between depression severity and HRQOL, evaluating the burden of concentration difficulties on HRQOL. METHODS: Six hundred ninety-two patients with unipolar depressive disorders recruited in 19 Italian centers answered a self-administered survey (SF-12 questionnaire, socio-demographic information). A psychiatrist completed a standardized data collection form encompassing a depression severity scale (MADRS) and clinical information. RESULTS: There was a strong graded association between the severity of depressive symptoms and both the physical (ω 2 = 0.13; p < 0.01) and mental (ω 2 = 0.34; p < 0.01) SF-12 domains. Additionally, we observed a strong association between concentration difficulties and all HRQOL outcomes independent of other symptoms of depression and robust to adjustment for possible confounders. CONCLUSIONS: Our data corroborate previous findings suggesting that cognitive impairment is a feature of unipolar depressive disorders partially independent of the severity of other symptoms, and may represent a specific target of therapy with a strong impact on patients' functioning and quality of life.

Estimating the Impact of Workplace Bullying: Humanistic and Economic Burden among Workers with Chronic Medical Conditions.

BACKGROUND: Although the prevalence of work-limiting diseases is increasing, the interplay between occupational exposures and chronic medical conditions remains largely uncharacterized. Research has shown the detrimental effects of workplace bullying but very little is known about the humanistic and productivity cost in victims with chronic illnesses. We sought to assess work productivity losses and health disutility associated with bullying among subjects with chronic medical conditions. METHODS: Participants (N = 1717) with chronic diseases answered a self-administered survey including sociodemographic and clinical data, workplace bullying experience, the SF-12 questionnaire, and the Work Productivity Activity Impairment questionnaire. RESULTS: The prevalence of significant impairment was higher among victims of workplace bullying as compared to nonvictims (SF-12 PCS: 55.5% versus 67.9%, p < 0.01; SF-12 MCS: 59.4% versus 74.3%, p < 0.01). The adjusted marginal overall productivity cost of workplace bullying ranged from 13.9% to 17.4%, corresponding to Italian Purchase Power Parity (PPP) 2010 US$ 4182-5236 yearly. Association estimates were independent and not moderated by concurrent medical conditions. CONCLUSIONS: Our findings demonstrate that the burden on workers' quality of life and productivity associated with workplace bullying is substantial. This study provides key data to inform policy-making and prioritize occupational health interventions.

Post-traumatic stress disorder among bank employee victims of robbery.

BACKGROUND: Post-traumatic stress disorder (PTSD) in the occupational context, especially following workplace robbery, is still under-investigated. AIMS: To evaluate PTSD incidence and risk factors among bank employee victims of robbery voluntarily joining an employer-sponsored post-robbery support programme. METHODS: The programme entailed a structured support interview with robbery victims within 15 days of the robbery and a follow-up psychological assessment 45 days after. A self-reported questionnaire on personal variables and robbery characteristics was administered to participants at the first support session (T1). Interviews on employees' psychophysical health and their opinion about the support programme were administered individually at follow-up (T2). The Impact of Event Scale (IES) was administered both at T1 and T2. RESULTS: There were 383 participants. At T2, 13% of subjects had an IES score >34, a cut-off suggestive of PTSD. In a multi-variate model, feelings of helplessness and terror during the robbery and the number of previous robberies were associated with a PTSD diagnosis. After including IES score at T1, other variables lost statistical significance. CONCLUSIONS: Our findings showed that PTSD is common among employee victims of workplace robbery. Our results also suggest the importance of subjective variables, such as personal perception of robbery severity and early emotional reaction, in identifying people at higher risk of developing PTSD.

Influence of blood pressure profile on frailty phenotype in community-dwelling elders in Brazil - FIBRA study.

Frailty is a clinical condition associated with pathological aging and biological vulnerability. In the spectrum of events related to frailty, aging of the cardiocirculatory system and abnormalities in arterial blood pressure (BP) partly explain the changes in tissue perfusion and, potentially, the decrease in physiological reserves. This study investigated the relationship between BP levels, systemic arterial hypertension (SAH) and the frailty phenotype by analyzing frailty criteria in a cross-sectional model into the FIBRA network, a populational sample of community-dwelling elders in Southeastern Brazil. Study participants with ≥65 years were selected by probabilistic sampling of residents in the urban area of the municipality of Campinas (n=900). Considering frailty as a whole and the difference between genders, there was a greater proportion of frail or pre-frail individuals among women than men. Analysis of individual frailty criteria showed that weight loss and fatigue were more common among women (18.3% vs. 12.5%, p=0.034 and 22.5% vs. 11.9%, p<0.001, respectively). Comparison of individuals with or without SAH failed to reveal any differences related to frailty criteria. Nevertheless, averages of diastolic blood pressure (DBP) and mean arterial blood pressure values were lower among elderly individuals with reduced grip strength, physical activity and the frailty classification as a whole (OR 0.986, IC 0.975-0.997) (for every 1 mmHg reduction in MBP values, the likelihood of being frail increased 1.4%). Our findings corroborate the relationship between BP values and frailty in the elderly and contribute to an understanding of the pathophysiological mechanisms of the syndrome.

Kinetics of amyloid and prion fibril formation in the absence and presence of dense shell sugar-decorated dendrimers.

The aggregation behavior of the amyloid peptide Aß(1-28) and the prion peptide PrP(185-208) - both responsible for neurodegenerative disorders - was analyzed in the absence and in the presence of poly(propylene imine) (PPI) dendrimers at generation 5 (G5) with a dense shell of maltose and maltotriose units. Thioflavin T (ThT) fluorescence assay and circular dichroism (CD) experiments indicated that fibril formation is enhanced at low dendrimer concentration, while it is prevented at relatively high dendrimer concentrations. Computer aided EPR analysis by means of the selected spin probe 4-octyl-dimethylammonium,2,2,6,6-tetramethyl-piperidine-1-oxyl bromide (CAT8) further demonstrated this behavior, but also provided detailed information on the mechanism of fibril formation and on the different behavior of the differently decorated dendrimers. The CAT8 radicals were progressively trapped at the peptide interphase when peptide aggregates were formed, also monitoring pre-fibrillar structures. At later time, a phase separation of the CAT8 radicals monitors the formation of further supramolecular structures where the probes become squeezed among fibrillar aggregates. The addition of small amounts of dendrimers promotes the formation of peptide fibrils breaking them and providing a larger amount of ends that serve as sites of replications. Conversely, a high amount of dendrimers allows the peptides to well separate from each other such preventing their aggregation. EPR results also indicate that the perturbation played by PPI(G5)-Maltose are more effective onto PrP(185-208) than onto Aß(1-28), while PPI(G5)-Maltotriose is less effective towards PrP(185-208) in both promoting aggregation and preventing it by changing the dendrimer concentration. These results provide useful information about the mechanism and interactions which regulate the ability of macromolecules like the dendrimers to favor, prevent or cure neurodegenerative diseases.

[Low-dose flutamide in the treatment of hyperandrogenism in adolescents]. / La flutamide a basse dosi nell'iperandrogenismo dell'adolescente.

AIM: The aim of the study was to evaluate the results of the use of flutamide at low doses for the therapy of the iperandrogenism in adolescents. METHODS: The study enrolled 35 young women with acne and irsutism; 31 had polycystic ovary syndrome (PCOS) and 4 periferic iperandrogenism. In other 8 young women, sexually active, the flutamide has been associated with the hormonal contraceptive. On the three young women with iperinsulinism it has been decided to associate the flutamide with the metformina. All the young women were checked each month for the liver functional. Before the beginning of the therapy the menstrual situation, the Body Mass Index (BMI), the Ferriman' s and Cremoncini's score, the ovary's ultrasound aspect, and the hormonal order were evaluated. Follow-up was made after three months and after six months after the beginning of the therapy with flutamide 62.5 mg/die. RESULTS: Only in 4 cases the therapy has been suspended due to collateral effects, soon regressed after one week of the treatment interruption. The results have demonstrated a overwhelming improvement of the peripheral symptoms of iperandrogenism in all patients. CONCLUSION: The authors hope that flutamide could enter in the list of medicines normally used to treat the beauty flaws of policistic acne and to restore a hormonal order associated to an effective contraception.

Low expression of APAF-1XL in acute myeloid leukemia may be associated with the failure of remission induction therapy.

Apoptotic protease activating factor 1 (APAF-1) has a critical role in the regulation of apoptosis. In the present study, the mRNA expression analysis of different APAF-1 transcripts (APAF-1S, APAF-1LC, APAF-1LN, and APAF-1XL) was analyzed in bone marrow samples from 37 patients with acute myeloid leukemia (newly diagnosed, with no previous treatment). APAF-1XL and APAF-1LN transcripts (with and without an extra WD-40 repeat region, respectively) were detected in all samples, although the major form expressed was APAF-1XL in 65% of the samples (group 1), while 35% of the samples expressed primarily APAF-1LN (group 2). Only 46% of the patients presented complete remission in response to remission induction therapy (represented by less than 5% marrow blasts and hematological recovery), all but 2 cases being from group 1, 21.6% did not attain complete remission (only 1 case from group 1), and 32.4% of the patients died early. Lower expression of APAF-1XL (APAF-1XL/APAF-1LN ratio <1.2) was associated with a poor response to therapy (P = 0.0005, Fisher exact test). Both groups showed similar characteristics regarding white blood cell counts, cytogenetic data or presence of gene rearrangements associated with good prognosis as AML1-ETO, CBFB-MYH11 and PML/RARA. Since it has been shown that only the isoforms with the extra WD-40 repeat region activate procaspase-9, we suggest that low procaspase-9 activation may also be involved in the deregulation of apoptosis and chemotherapy resistance in acute myeloid leukemia.

Identification of differentially expressed genes induced by hydroxyurea in reticulocytes from sickle cell anaemia patients.

1. The major effect associated with hydroxyurea (HU) treatment of sickle cell anaemia (SCA) patients is an increase in fetal haemoglobin (HbF) synthesis, which inhibits the polymerization of haemoglobin S. 2. Hydroxyurea improves clinical symptoms by reducing the frequency of pain and vaso-occlusive crises, acute chest syndrome, transfusion requirements and hospitalization. 3. The molecular mechanisms responsible for HU-mediated induction of fetal globin transcription are not completely understood. Therefore, the aim of the present study was to identify differentially expressed genes participating in these mechanisms. 4. We established two suppression subtractive hybridization (SSH) libraries from reticulocytes obtained from SCA patients either not on or on HU treatment. The gene expression of some of the genes identified was subsequently evaluated by real-time polymerase chain reaction (PCR). 5. Genes identified with altered expression included SUDS3, FZD5 and PHC3, which may be associated with the regulation of globin expression. 6. This is the first demonstration of an association between HU treatment and the expression of genes identified in erythroid cells.

Hb Indianapolis [beta112 (G14) Cys-->Arg] as the probable cause of moderate hemolytic anemia and renal damage in a Brazilian patient.

Hemoglobin (Hb) Indianapolis [beta112 (G14) Cys-->Arg] is a rare and slightly unstable beta-globin variant. All carriers described to date were clinically normal with only mild reticulocytosis. We report here a case of a Brazilian patient in whom hemolytic anemia and acute renal failure were probably caused by the presence of this variant.

An overview of the ultraviolet index and the skin cancer cases in Brazil.

This study relates regional and seasonal UV index (UVI) variations, number of skin cancer cases and population skin-color distribution in Brazil. UVI calculations were performed using the UV Global Atmospheric Model (UVGAME), whose characteristics and validations are provided in thiis article. Health and racial data sets are based on the health and census data collected by Brazilian governmental agencies in the past. The discussion covers cultural customs and details of health and educational campaigns in Brazil. Despite lower UV levels in the South and Southeast regions, the results show a number of nonmelanoma skin cancer (NMSC) cases regions, where the white population is predominant. In general, in the southern regions about 50 new NMSC cases per 100000 inhabitants have been diagnosed each year. These rates decrease almost 40% in the Central-North regions and more than 80% in Northeast region, where miscegenation is common. In addition, the UVI evaluation is extended to other South American sites with singular characteristics, e.g. populous cities located in high altitudes or those affected by the Antarctic ozone hole in the extreme south of the continent.

Molecular identification of Sicilian (deltabeta) degrees-thalassemia associated with beta-thalassemia and hemoglobin S in Brazil.

We describe the clinical and molecular characteristics of two unrelated Brazilian families with an association of the Sicilian form of (deltabeta) degrees -thalassemia with hemoglobin S and beta-thalassemia. Direct sequencing of the beta-globin gene showed only the hemoglobin S mutation in patient 1 and the beta-thalassemia IVS1-110 in patient 2. The other allele was deleted in both patients and PCR of DNA samples of the breakpoint region of both patients showed a band of approximately 1,150 bp, expected to be observed in the DNA of carriers of Sicilian (deltabeta) degrees -thalassemia. The nucleotide sequence of this fragment confirmed the Sicilian deletion. There are few reports concerning the Hb S/(deltabeta) degrees -thalassemia association and patient 2 is the first reported case of Sicilian type of (deltabeta) degrees -thalassemia in association with beta-thalassemia documented at the molecular level.

Molecular identification of Sicilian (deltaß)º-thalassemia associated with ß-thalassemia and hemoglobin S in Brazil

We describe the clinical and molecular characteristics of two unrelated Brazilian families with an association of the Sicilian form of (deltaß)º-thalassemia with hemoglobin S and ß-thalassemia. Direct sequencing of the ß-globin gene showed only the hemoglobin S mutation in patient 1 and the ß-thalassemia IVS1-110 in patient 2. The other allele was deleted in both patients and PCR of DNA samples of the breakpoint region of both patients showed a band of approximately 1,150 bp, expected to be observed in the DNA of carriers of Sicilian (deltaß)º-thalassemia. The nucleotide sequence of this fragment confirmed the Sicilian deletion. There are few reports concerning the Hb S/(deltaß)º-thalassemia association and patient 2 is the first reported case of Sicilian type of (deltaß)º-thalassemia in association with ß-thalassemia documented at the molecular level

Renal SPECT with Tc-99m DMSA in children with upper urinary tract infections using a triple-headed gamma camera.

UNLABELLED: Renal cortical scintigraphy with Tc-99m DMSA provides an excellent imaging modality for the assessment of cortical damage secondary to upper urinary tract infection (UTI). METHODS: The authors evaluated 48 children with UTI, 12 of whom had a history of vescico-ureteral reflux (from first of fourth degree), by planar scintigraphy and SPECT using a triple-headed gamma camera equipped with parallel-hole, high-resolution collimators. RESULTS: SPECT images yielded positive findings in 36 kidneys, whereas planar scans yielded positive findings in 18 kidneys. The total number of lesions detected by SPECT was 51, whereas the number found with the planar technique was 23. CONCLUSION: This study demonstrates the superiority of SPECT scanning in detecting kidney lesions in children with UTI.

[Therapeutic abortion intrauterine fetal death in the second trimester. Treatment with a gemeprost-sulprostone combination]. / L'aborto terapeutico e la morte endouterina del feto nel secondo trimestre. Trattamento mediante impiego combinato gemeprost-sulprostone.

UNLABELLED: This study reports the results obtained in the medical introduction of abortion during the second trimester of pregnancy in 52 patients following intrauterine fetal death or the diagnosis of fetal malformations. METHODS: The protocol consisted of the alternate use of intravaginal suppositories of gemeprost and intramuscular injections of sulprostone. The results were analysed using statistical methods and evaluated in relation to the different parameters present (intrauterine fetal death or therapeutic abortion, maternal age, gestation period and parity). RESULTS: It was seen that the time required to induce abortive labour was significantly shorter in patients with IFD compared to patients with live fetus. The comparison between patients with a gestation period < or > 18 weeks revealed shorter induction times in the former group without reaching statistical significance. CONCLUSIONS: Maternal age (under and over 30) and parity (P = 0 and P > or = 1) did not influence the results obtained.
